# Docker Manage Docker container and image management. ## Containers ```bash # Status overview docker ps -a --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}\t{{.Image}}" # Resource usage docker stats --no-stream --format "table {{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}" # Logs docker logs --tail 50 <container> docker logs --since 1h <container> # Lifecycle docker restart <container> docker stop <container> docker start <container> ``` ## Images ```bash docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}\t{{.CreatedSince}}" docker pull <image>:<tag> docker image prune -f # remove dangling ``` ## Docker Compose ```bash docker compose ps docker compose up -d <service> docker compose logs -f --tail 100 <service> docker compose restart <service> docker compose pull && docker compose up -d # update all ``` ## Health Checks ```bash # Check container health docker inspect --format='{{.State.Health.Status}}' <container> # All unhealthy containers docker ps --filter health=unhealthy ``` ## Troubleshooting ```bash # Shell into container docker exec -it <container> sh # Port conflicts docker ps --format "{{.Ports}}" | sort # Disk usage docker system df # Network inspect docker network ls docker network inspect <network> ``` ## Safety Always confirm before: - `docker rm` / `docker rmi` - `docker system prune` - `docker compose down -v` (removes volumes!)
